The Center for Radiative Shock Hydrodynamics (CRASH) is advancing predictive science in the nationally important area of radiation hydrodynamics (RH) via a unified, multi-prong approach. To substantially improve the ability to do predictive simulations of high - energy - density and astrophysical flows, Center researchers are:

Developing a software framework for RH to serve as a testbed for development, verification and validation of RH modeling elements.

Developing a system for hierarchically validating the software framework.

Extending an existing experimental effort, centered on radiative shocks, to obtain data and quantify uncertainties in the experiments.

Simulating these experiements and quantifying the accuracy of the simulations.

Establishing a doctoral program for Predictive Science and Engineering.

Team Expertise

The CRASH team, comprised of researchers from the University of Michigan and Texas A&M University, are experts in:

Numerical methods for fluids, plasmas, and radiation transport

Uncertainty quantification and propagation

High - energy - density physics experiments and theory

Applied mathematics

Software engineering and computer science

Parallelization of radiation transport algorithms

The potential impacts of the project include NNSA lab use of advanced methods in radiation hydrodynamic simulations and methods for uncertainty quantification developed in the Center and the hiring by the laboratories of people trained in predictive radiation hydrodynamics through the Center.
